熨平板和摊铺机 Screed and paver

技术领域 Technical field

本发明涉及摊铺机领域，具体地，涉及一种熨平板和具有该熨平板的摊铺机。背景技术 The present invention relates to the field of pavers, and in particular to a screed and a paver having the screed. Background technique

用于摊铺机的熨平板主要可分为机械加长式熨平板和液压伸缩式熨平板。机械加长式熨平板通常是采用螺栓等紧固件将基本熨平板和若干加长熨平板组装成所需作业宽度的熨平板，其结构简单，整体刚度好，布料均匀。液压伸缩式熨平板通常是在主熨平板的两侧插接有副熨平板，主副熨平板之间可通过液压缸的伸缩运动来无级调节整个熨平板的作业宽度，其宽度调节方便省力，但整体刚度较差，在调整不当时会影响摊铺质量。现有技术中还有采用混合式熨平板，即混合使用上述两种主要结构，例如在液压伸缩式熨平板的外侧再通过螺栓等紧固件连接加长熨平板，其工作原理与上述两种主要结构基本相同。 Stencils for pavers are mainly divided into mechanical extension screeds and hydraulic telescopic screeds. Mechanically extended screeds are typically screeds that use a fastener such as a bolt to assemble a basic screed and lengthened screed into a desired working width. The structure is simple, the overall stiffness is good, and the fabric is even. The hydraulic telescopic screed usually has a secondary screed inserted on both sides of the main screed. The main screed can adjust the working width of the screed steplessly through the telescopic movement of the hydraulic cylinder. The width adjustment is convenient and labor-saving. However, the overall rigidity is poor, and the quality of the paving will be affected when the adjustment is not proper. In the prior art, a hybrid screed is also used, that is, the above two main structures are mixed and mixed, for example, on the outer side of the hydraulic telescopic screed, the screed is connected by a fastener such as a bolt, and the working principle and the above two main The structure is basically the same.

图 1 显示了一种机械加长式熨平板，包括两个熨平板单元（即基本熨平板和加长熨平板），每个熨平板单元具有前挡板。从图 1中可以看出，在这种熨平板中，在两个熨平板单元的前挡板之间不可避免地会存在缝隙，在作业时，摊铺物料可能会沿着该缝隙挤压渗透到前挡板的后方，导致后面的夯锤机构因物料粘滞而不能顺畅地进行夯击动作，从而影响对摊铺物料的预压实效果，继而影响整个路面的摊铺质量。发明内容 Figure 1 shows a mechanical extended screed that includes two screed units (ie, a basic screed and an extended screed), each screed unit having a front bezel. As can be seen from Figure 1, in this screed, there is inevitably a gap between the front baffles of the two screed units, during which the paving material may squeeze through the gap. When it reaches the rear of the front baffle, the rear tamper mechanism cannot smoothly perform the slamming action due to the viscous material, thereby affecting the pre-compacting effect on the paving material, which in turn affects the paving quality of the entire pavement. Summary of the invention

以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。 The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are intended to be illustrative and not restrictive.

在本发明中，在未作相反说明的情况下，使用的方位词如 "上、下、左、右、前、后"通常是针对摊铺机的正常行驶方向而言的。 In the present invention, the orientation words used, such as "up, down, left, right, front, and rear," are generally for the normal traveling direction of the paver, unless otherwise stated.

如图 2所示，作为本发明总的发明构思，提供了一种熨平板，至少包括相互连接的两个熨平板单元 10，每个熨平板单元 10包括前挡板 11，所述熨平板还包括封料板 20和锁紧装置 30，所述封料板 20通过所述锁紧装置 30可松开地锁紧到至少一个所述前挡板 11上以遮盖所述前挡板 11之间的缝隙 12。 As shown in FIG. 2, as a general inventive concept of the present invention, there is provided a screed comprising at least two screed units 10 connected to each other, each screed unit 10 including a front bezel 11, and the screed further The sealing plate 20 and the locking device 30 are included, and the sealing plate 20 is releasably locked to the at least one front baffle 11 by the locking device 30 to cover the front baffle 11 The gap of 12.

本发明主要应用于机械加长式熨平板，当然也可应用于具有机械加长式结构的混合式熨平板。无论是何种形式，该熨平板至少具有两个熨平板单元，此处所指的熨平板单元的概念既包括基本熨平板，也包括加长熨平板。换言之，本发明的封料板可以应用于基本熨平板和加长熨平板之间，也可应用于两个加长熨平板之间，只要两个熨平板单元相互连接且二者之间自然形成有缝隙即可。另外，对于整个摊铺机而言，本发明的封料板优选应用于所有相邻两个熨平板单元之间，以获得最佳的整体密封效果。 The invention is primarily applicable to mechanically extended screeds and, of course, to hybrid screeds having a mechanically elongated configuration. Regardless of the form, the screed has at least two screed units, and the concept of the screed unit referred to herein includes both a basic screed and an extended screed. In other words, the sealing plate of the present invention can be applied between a basic screed and an extended screed, and can also be applied between two elongated screeds, as long as the two screed units are connected to each other and a gap is naturally formed therebetween. Just fine. Additionally, for the entire paver, the closure panel of the present invention is preferably applied between all adjacent two screed units for optimum overall sealing.

参见图 1，熨平板单元 10通常包括熨平板箱体 100和位于该箱体前面的前挡板 11，夯锤机构 200—般设置在熨平板箱体 100内。在相邻两个熨平板单元 10相互拼接时，缝隙 12形成于两个前挡板 11之间。在本发明的技术方案中，如图 2所示，提供了一种封料板 20，该封料板 20能够通过锁紧装置 30可松开地锁紧到至少一个前挡板 11上以遮盖两个前挡板 11之间的缝隙 12，从而可以避免摊铺物料通过该缝隙 12进入前挡板 11的后面，对前挡板 11后面的夯锤机构 200或其他零部件造成不利影响。图 2中的附图标记 14表示形成于前挡板后表面上的边筋板，对前挡板 11起到加强作用。附图标记 15表示前挡板耳座， 16表示前挡板挂钩，用于将前挡板 11 连接到熨平板箱体 100上。 Referring to FIG. 1, the screed unit 10 generally includes a screed case 100 and a front bezel 11 on the front of the case, and the tamper mechanism 200 is generally disposed within the screed case 100. When two adjacent screed units 10 are spliced to each other, a slit 12 is formed between the two front bezels 11. In the technical solution of the present invention, as shown in FIG. 2, a sealing plate 20 is provided, which can be loosely locked to at least one front bezel 11 by a locking device 30 to cover The gap 12 between the two front baffles 11 prevents the paving material from entering the rear of the front baffle 11 through the slit 12, adversely affecting the tamper mechanism 200 or other components behind the front baffle 11. Reference numeral 14 in Fig. 2 denotes a side rib formed on the rear surface of the front bezel to reinforce the front bezel 11 use. Reference numeral 15 denotes a front bezel ear, and 16 denotes a front bezel hook for connecting the front bezel 11 to the screed case 100.

在本发明的技术方案中，一方面，通过封料板 20可以遮蔽两个前挡板 11之间的缝隙 12，基本上能够避免摊铺物料通过该缝隙 12流入到前挡板 11的后方；另一方面，由于封料板 20是通过锁紧装置 30可松开地锁紧到前挡板 11上，因此，封料板 20的拆装就变得非常方便，在两个熨平板单元 10拼接之后，通过锁紧装置 30可以方便地安装封料板 20，在前挡板 11 受损或由于其他原因而需要拆卸或更换时，将封料板 20拆卸之后，就可以方便地拆卸前挡板 11，操作非常简便。 In the technical solution of the present invention, on the one hand, the gap 12 between the two front bezels 11 can be shielded by the sealing plate 20, and the paving material can be substantially prevented from flowing into the rear of the front baffle 11 through the slit 12; On the other hand, since the sealing plate 20 is releasably locked to the front bezel 11 by the locking device 30, the attachment and detachment of the sealing plate 20 becomes very convenient, in the two screed units 10 After splicing, the sealing plate 20 can be conveniently installed by the locking device 30. When the front dam 11 is damaged or needs to be disassembled or replaced for other reasons, the front plate can be easily removed after the sealing plate 20 is detached. Board 11, easy to operate.

在本发明中，封料板 20可以安装到前挡板 11 的前表面上，也可以安装到前挡板 11的后表面上，甚至为了获得最优的密封效果，还可以在前表面和后表面上均安装封料板 20。 In the present invention, the sealing plate 20 may be attached to the front surface of the front bezel 11, or may be attached to the rear surface of the front bezel 11, even in order to obtain an optimum sealing effect, on the front surface and the rear. A sealing plate 20 is mounted on the surface.

作为一种优选的实施方式，如图 2所示，将封料板 20安装到前挡板 11 的后表面上。通过这种方式，可以避免摊铺物料（例如混凝土、沥青等）对封料板 20和锁紧装置 30造成不利影响，例如在混凝土直接接触封料板 20和锁紧装置 30—段时间之后而固化时，可能会造成无法顺利地松开锁紧装置 30以及将封料板 20从前挡板 11上顺利取下的问题。 As a preferred embodiment, as shown in Fig. 2, the sealing plate 20 is attached to the rear surface of the front bezel 11. In this way, it is possible to prevent the paving material (e.g., concrete, asphalt, etc.) from adversely affecting the sealing plate 20 and the locking device 30, for example, after the concrete directly contacts the sealing plate 20 and the locking device 30. When it is cured, there may be a problem that the locking device 30 cannot be smoothly released and the sealing plate 20 is smoothly removed from the front bezel 11.

另外，如图 2和图 3所示，在现有设计中，前挡板 11的顶部通常设计成向后弯曲的形状，这种向后弯曲的顶部与前挡板 11左右两侧的侧筋板 14 共同形成一种框架式的结构，从而能够增强前挡板 11的整体强度。另外，向后弯曲的顶部还可以方便地与熨平板上方的盖板（未图示）进行连接。在这种情况下，相邻的两个前挡板 11的顶部优选形成有相对的缺口 13，封料板 20可以通过该对缺口 13***到前挡板 11的后表面，并且封料板 20 的上端从该对缺口 13中向上露出。也就是说，在安装封料板 20时，可以使封料板 20从前挡板 11顶部的一对缺口 13处从上向下贴着前挡板 11的后表面***，因此安装比较方便。另外，在封料板 20***到位之后，封料板 20的上端优选能够从缺口 13中向上露出，由此在需要拆卸封料板 20时，可以通过该露出的上端方便地将封料板 20向上拔出，因此封料板 20拆卸更加方便。另外，为了使封料板 20的拆装更加方便，进一步优选地，封料板 20的上端可以形成有操作孔 21，利用该操作孔 21可以使用一些适当的工具辅助封料板 20的拆装作业，操作更方便。 In addition, as shown in FIG. 2 and FIG. 3, in the prior design, the top of the front bezel 11 is generally designed to be bent backward, and the rearwardly curved top and the left and right side ribs of the front bezel 11 are ribbed. The plates 14 together form a frame-like structure to enhance the overall strength of the front bezel 11. In addition, the rearwardly curved top can be conveniently attached to a cover (not shown) above the screed. In this case, the tops of the adjacent two front bezels 11 are preferably formed with opposite notches 13, through which the sealing sheet 20 can be inserted into the rear surface of the front bezel 11, and the sealing plate 20 The upper end is exposed upward from the pair of notches 13. That is, when the sealing plate 20 is installed, the sealing plate 20 can be inserted from the upper and lower sides of the front bezel 11 from the pair of notches 13 at the top of the front bezel 11 so that the mounting is convenient. In addition, after the sealing plate 20 is inserted into place, the sealing material The upper end of the plate 20 is preferably exposed upwardly from the notch 13, whereby the sealing plate 20 can be easily pulled upward through the exposed upper end when the sealing plate 20 needs to be removed, so that the sealing plate 20 is more easily removed. In addition, in order to facilitate the disassembly and assembly of the sealing plate 20, it is further preferred that the upper end of the sealing plate 20 can be formed with an operation hole 21, by which the appropriate sealing tool 20 can be used to assist the disassembly and assembly of the sealing plate 20. Homework, operation is more convenient.

此外，从图 2和图 3中还可以看出，前挡板 11的下部通常设计成向后下方倾斜。在这种情况下，在将封料板 20从前挡板 11顶部的缺口 13向下 ***时，封料板 20的下端也将朝向后下方倾斜，即贴着前挡板 11 的后表面行进，从而基本上能够遮蔽前挡板 11之间缝隙 12的整个长度。 Further, as can be seen from Figs. 2 and 3, the lower portion of the front flap 11 is generally designed to be inclined rearward and downward. In this case, when the sealing plate 20 is inserted downward from the notch 13 at the top of the front bezel 11, the lower end of the sealing plate 20 is also inclined toward the rear lower side, that is, against the rear surface of the front bezel 11, Thereby, the entire length of the gap 12 between the front bezels 11 can be substantially shielded.

如上所述，封料板 20可以通过锁紧装置 30可松开地锁紧到至少一个前挡板 11上，即只要能够将封料板 20固定到前挡板 11上以遮蔽相邻两个前挡板 11之间的缝隙 13即可。优选地，如图 2所示，封料板 20通过两个对称设置的锁紧装置 30可松开地锁紧到相邻的两个前挡板 11上，由于封料板 20的两侧通过对称的两个锁紧装置 30同时锁紧到两个前挡板 11上，因此封料板 20两侧受力均衡，一方面可以避免封料板 20两侧由于受力不均而发生变形，另一方面能够很好地保证封料板 20的两侧与两个前挡板 11 之间都能够紧紧地贴合在一起，以防止摊铺物料通过两个前挡板 11之间的缝隙 13以及封料板 20的两侧与前挡板 11之间的间隙流入，切实保证了封料板 20对前挡板 11之间缝隙 13的遮蔽效果。两个对称设置的锁紧装置 30 彼此间隔开以免发生干涉。 As described above, the sealing plate 20 can be releasably locked to the at least one front bezel 11 by the locking device 30, that is, as long as the sealing plate 20 can be fixed to the front bezel 11 to shield the adjacent two The gap 13 between the front baffles 11 is sufficient. Preferably, as shown in FIG. 2, the sealing plate 20 is releasably locked to the adjacent two front bezels 11 by two symmetrically disposed locking devices 30, as both sides of the sealing plate 20 pass The two symmetrical locking devices 30 are simultaneously locked to the two front baffles 11 , so that the two sides of the sealing plate 20 are balanced by force, and on the one hand, the deformation of both sides of the sealing plate 20 due to uneven force can be avoided. On the other hand, it can be well ensured that both sides of the sealing plate 20 and the two front baffles 11 can be tightly fitted together to prevent the paving material from passing through the gap between the two front baffles 11 13 and the gap between the both sides of the sealing plate 20 and the front baffle 11 flow in, which ensures the shielding effect of the sealing plate 20 on the gap 13 between the front baffles 11. Two symmetrically disposed locking devices 30 are spaced apart from one another to avoid interference.

在本发明中，锁紧装置可以具有多种形式。下面，将通过优选的实施方式对锁紧装置进行详细描述，但需要说明的是，本发明并不局限于这些特定结构的锁紧装置。根据本发明的构思，本领域技术人员可以想到一些其他结构的锁紧装置并将其应用到本发明中，其同样应当落入到本发明的保护范围之内。 In the present invention, the locking device can have a variety of forms. In the following, the locking device will be described in detail by way of a preferred embodiment, but it should be noted that the invention is not limited to the locking device of these specific configurations. In accordance with the teachings of the present invention, those skilled in the art will recognize a number of other configurations of locking devices and apply them to the present invention, which are also intended to fall within the scope of the present invention.

如图 4和图 5所示，根据一种优选的实施方式，锁紧装置 30可以包括安装座 31，该安装座 31的一端固定在前挡板 11上，该安装座 31的另一端朝向封料板 20延伸，并与前挡板 11之间具有间隙以容纳封料板 20。在这种实施方式中，安装座 31—端可以通过焊接或者紧固件连接等方式固定在前挡板 11上，另一端朝向封料板 20延伸并与前挡板 11之间形成有供封料板 20穿过的间隙，因此封料板 20在从上向下***时，可以穿过该间隙并通过该间隙保持，因此这种锁紧装置结构非常简单，并且封料板 20拆装也非常方便。如图中所示，一对安装座 31沿封料板的宽度方向对称设置，从而封料板 20的两侧都可以通过该对安装座 31锁紧到前挡板的后表面上。为了便于封料板 20***到该间隙中，安装座 31 的另一端的内表面（即与封料板 20或者前挡板 11相对的表面）优选可以形成有楔形面，即该内表面上端与前挡板 11之间的距离大于下端与前挡板 11之间的距离，因此，一方面，由于内表面上端与前挡板 11之间的距离较大，所以封料板 20能够顺利地***到该间隙中；另一方面，因为内表面下端与前挡板 11之间的距离较小，所以能够将封料板 20紧紧地锁紧到前挡板 11 的后表面，保证封料板 20与前挡板 11之间的密封性，有效防止摊铺物料通过前挡板 11之间的缝隙 13以及封料板 20和前挡板 11之间的间隙流入到前挡板 11的后方。 As shown in Figures 4 and 5, according to a preferred embodiment, the locking device 30 can comprise The mounting seat 31 has one end fixed to the front baffle 11 and the other end of the mounting seat 31 extending toward the sealing plate 20 and having a gap with the front baffle 11 to accommodate the sealing plate 20. In this embodiment, the mounting seat 31-end may be fixed to the front baffle 11 by welding or fastener connection, and the other end may extend toward the sealing plate 20 and form a seal with the front baffle 11. The gap through which the plate 20 passes, so that the sealing plate 20 can pass through the gap and be retained through the gap when inserted from the top to the bottom, so that the locking device is very simple in structure, and the sealing plate 20 is also disassembled. Very convenient. As shown in the figure, a pair of mounts 31 are symmetrically disposed along the width direction of the sealing plate so that both sides of the sealing plate 20 can be locked to the rear surface of the front bezel by the pair of mounts 31. In order to facilitate the insertion of the sealing plate 20 into the gap, the inner surface of the other end of the mounting seat 31 (i.e., the surface opposite to the sealing plate 20 or the front baffle 11) may preferably be formed with a wedge-shaped surface, that is, the upper end of the inner surface is The distance between the front baffles 11 is greater than the distance between the lower end and the front baffle 11, and therefore, on the one hand, since the distance between the upper end of the inner surface and the front baffle 11 is large, the sealing plate 20 can be smoothly inserted. In the gap; on the other hand, because the distance between the lower end of the inner surface and the front baffle 11 is small, the sealing plate 20 can be tightly locked to the rear surface of the front baffle 11 to ensure the sealing plate The seal between the 20 and the front bezel 11 effectively prevents the spread material from flowing into the rear of the front flap 11 through the gap 13 between the front bezel 11 and the gap between the sealing plate 20 and the front bezel 11.

固定座 31优选形成为 L形，该 L形的一端固定到前挡板 11上，另一端与前挡板 11之间自然形成间隙供封料板 20从中穿过。 L形固定座 31结构简单，强度高，使用可靠性高。 The holder 31 is preferably formed in an L shape, one end of which is fixed to the front bezel 11, and a gap is formed between the other end and the front bezel 11 for the sealing sheet 20 to pass therethrough. The L-shaped mount 31 has a simple structure, high strength, and high reliability.

为了增强封料板和前挡板之间的密封性，出了采用楔形面的方案之外，还可以采用紧固件的方式。 gP，安装座 31的另一端可以通过紧固件（未图示）将所述封料板 20压紧在所述前挡板 11上。例如，可以在固定座 31的另一端形成螺紋孔 32，在封料板 20***到位之后，将紧定螺钉等通过该螺紋孔 32拧入，以便将封料板 20牢固地压紧到前挡板 11的后表面上。若需拆卸封料板 20，将螺钉拆下，然后将封料板 20向上拔出即可。另外需要说明的是，这种实施方式也可以与上述楔形面的实施方式组合使用，本发明对此不再赘述。 In order to enhance the sealing between the sealing plate and the front baffle, in addition to the wedge-shaped surface, a fastener can also be used. gP, the other end of the mount 31 can press the sealing plate 20 against the front baffle 11 by fasteners (not shown). For example, a screw hole 32 may be formed at the other end of the fixing base 31, and after the sealing plate 20 is inserted into position, a set screw or the like is screwed through the screw hole 32 to firmly press the sealing plate 20 to the front end. On the back surface of the board 11. If the sealing plate 20 needs to be removed, the screws are removed, and then the sealing plate 20 is pulled up. Also need to say It is to be understood that this embodiment can also be used in combination with the embodiment of the wedge face described above, and the present invention will not be described again.

作为另一种优选的实施方式，如图 6所示，锁紧装置 30可以包括安装座 31和转动压板 33，安装座 31固定在前挡板 11上，转动压板 33可转动地安装在安装座 31上，转动压板 33的与前挡板 11相对的表面（可称之为内表面）上形成有楔形面，以便在转动压板 33相对于安装座 31转动时能够通过楔形面将封料板 20压紧在前挡板 11上。在这种实施方式中，通过转动压板 33，也可以方便地将封料板 20锁紧到前挡板 11上。例如，在封料板 20***到位之后，将转动压板 33转过一个角度，从而可以通过其内表面上的楔形面将封料板 20紧紧地压紧在前挡板 11上。若需要拆卸封料板 20，使转动压板 33反向转过相应的角度即可。 As another preferred embodiment, as shown in FIG. 6, the locking device 30 may include a mounting seat 31 and a rotating pressure plate 33. The mounting seat 31 is fixed to the front bezel 11, and the rotating pressing plate 33 is rotatably mounted on the mounting seat. 31, a surface of the rotating platen 33 opposite to the front baffle 11 (which may be referred to as an inner surface) is formed with a wedge-shaped surface so that the sealing plate 20 can be passed through the wedge surface when the rotating platen 33 is rotated relative to the mounting seat 31. Pressed on the front bezel 11. In this embodiment, the sealing plate 20 can also be conveniently locked to the front flap 11 by rotating the pressure plate 33. For example, after the sealing plate 20 is inserted into position, the rotating platen 33 is rotated through an angle so that the sealing plate 20 can be tightly pressed against the front flap 11 by the tapered surface on the inner surface thereof. If it is necessary to disassemble the sealing plate 20, the rotating platen 33 can be reversely rotated through the corresponding angle.

The inner surface of the rotary platen 33 has a convex portion 35 which will be touched when the sealing plate 20 is inserted downward from the top of the front baffle 11, so that the rotary platen 33 is rotated downward against the biasing force of the elastic member 34. Thereby, the sealing plate 20 can be pressed onto the front baffle 11.

优选地，转动压板 33可以形成为具有第一臂部 36和第二臂部 37的 V 形，第一臂部 36和第二臂部 37的结合处可转动地安装在安装座 31上，凸起部 35形成在第一臂部 36上，楔形面则形成在所述第二臂部 37上。 Preferably, the rotary platen 33 may be formed in a V shape having a first arm portion 36 and a second arm portion 37, and a joint of the first arm portion 36 and the second arm portion 37 is rotatably mounted on the mount 31, convex The starting portion 35 is formed on the first arm portion 36, and the wedge-shaped surface is formed on the second arm portion 37.

作为更具体的实施例，从图 10中还可以看出，弹性件 34优选使用螺旋弹簧，该螺旋弹簧套装在固定座 31上，螺旋弹簧的一端偏压在转动压板 33内表面上的凸起部 35上，另一端可以抵靠在前挡板 11后表面上的筋板 14上。转动压板 33通过其安装孔 331可转动地套装在安装座 31上，更具地，套装在安装座 31的凸台上，然后通过螺钉 39定位。 As a more specific embodiment, it can also be seen from Fig. 10 that the elastic member 34 preferably uses a coil spring which is fitted over the fixing base 31, and one end of the coil spring is biased against the projection on the inner surface of the rotary platen 33. On the portion 35, the other end can abut against the rib 14 on the rear surface of the front bezel 11. The rotary platen 33 is rotatably fitted to the mount 31 through its mounting hole 331, and more specifically, is fitted to the boss of the mount 31, and then positioned by the screw 39.

下面结合图 7和图 8对这种实施方式的工作过程进行简单描述，其中图 7表示已经安装了封料板 20的情况，图 8表示没有安装封料板 20的情况。如图所示，在将封料板 20从前挡板 11顶端的缺口 13向下***时，封料板 20的下端将接触转动压板 33内表面上的凸起部 35，从而通过该凸起部 35带动转动压板 33克服弹性件 34的偏压力而向下转动，直到凸起部 35 离开封料板 20的下端而变成与封料板 20的侧面相接触，此时转动压板 33 的第二臂部 37将转动到与封料板 20相对的位置，将封料板 20紧紧地压靠在前挡板 11 的内表面上。在将封料板 20向上拔出时，其工作过程相反，不再赘述。通过这种方式，可以非常方便、快捷地拆装封料板。 The working process of this embodiment will be briefly described below with reference to Figs. 7 and 8, wherein Fig. 7 shows the case where the sealing plate 20 has been installed, and Fig. 8 shows the case where the sealing plate 20 is not installed. Condition. As shown, when the sealing plate 20 is inserted downward from the notch 13 at the top end of the front bezel 11, the lower end of the sealing plate 20 will contact the projection 35 on the inner surface of the rotating platen 33, thereby passing the projection 35 drives the rotary platen 33 to rotate downward against the biasing force of the elastic member 34 until the convex portion 35 leaves the lower end of the sealing plate 20 to become in contact with the side surface of the sealing plate 20, and at this time rotates the second portion of the pressure plate 33. The arm portion 37 will be rotated to a position opposite to the sealing plate 20, and the sealing plate 20 is pressed tightly against the inner surface of the front bezel 11. When the sealing plate 20 is pulled up, the working process is reversed and will not be described again. In this way, the sealing plate can be removed and removed very conveniently and quickly.
