Description

Technical Field

[0001] This application relates to the field of mattress spring extrusion molding technology, specifically to an extrusion molding structure for a mattress spring processing device. Background Technology

[0002] In the mattress spring manufacturing industry, traditional processing methods have many drawbacks. On the one hand, it is difficult to flexibly control the spring pitch, resulting in mattress springs of uniform specifications that cannot meet the market's demand for diverse mattress functions, such as the need for springs with different support levels in different areas to improve the mattress's wrapping and support for the body. On the other hand, adjusting the structure of springs with different pitches using traditional equipment is complex and cumbersome, consuming a lot of time and manpower, severely impacting production efficiency. Furthermore, the lack of precision in guiding the springs during processing leads to poor spring forming quality, affecting the overall quality of the mattress.

[0003] Therefore, there is a need for an extrusion molding structure for mattress spring processing equipment that can flexibly control spring pitch, facilitate production structure adjustment, efficiently complete production processes, and ensure spring molding quality. Summary of the Invention

[0004] To address the aforementioned technical problems, this application solves the issues of traditional mattress spring processing, such as difficulty in flexibly controlling spring pitch, producing products of different specifications, inconvenient operation, and low production efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: an extrusion molding structure for a mattress spring processing device, comprising a mounting plate, an upper mounting rod and a lower mounting plate fixedly mounted on the mounting plate, an arc-shaped plate fixedly mounted on the upper connecting rod and the lower mounting plate, the arc-shaped plate having a semi-circular structure, an inlet groove and a rectangular groove provided on the arc-shaped plate, an outer mounting block fixedly mounted on the rectangular groove, a plurality of circular sliding grooves provided on the outer mounting block, a retaining shaft slidably mounted on the circular sliding grooves, an inner mounting block fixedly mounted on the retaining shaft, the inner mounting block being located on the side enclosed by the arc-shaped structure of the arc-shaped plate, a plurality of guide plates for guiding the direction of the spring fixedly mounted on the inner mounting block, an outer rotating shaft rotatably mounted on the lower mounting plate, an outer rotating rod fixedly mounted on the outer rotating shaft, and the processed mattress spring being pushed away from the guide plates and the arc-shaped plate by the outer rotating rod.

[0006] To better realize this application, the guide piece further includes a first inner guide piece, a first outer guide piece, a second inner guide piece, and a second outer guide piece. The first inner guide piece and the first outer guide piece are a group and are disposed on an inner mounting block. The second inner guide piece and the second outer guide piece are a group and are disposed on an inner mounting block. The outer mounting block is provided with multiple inner mounting blocks with different guide pieces. By setting the arrangement of the inner mounting blocks, the pitch of the mattress springs produced can be changed.

[0007] To better realize this application, the guide piece is further described as having a spiral structure, with its outer edge rotatably connected to the inner arc surface of the arc-shaped plate.

[0008] To better realize this application, the outer mounting block is further provided with a bracket, on which an upper connecting shaft is rotatably mounted. The upper connecting shaft is provided with multiple sets of limiting components, each including an upper connecting rod, a torsion spring, and a lower connecting rod. The upper connecting rod is rotatably mounted on the upper connecting shaft, and the torsion spring is sleeved on the upper connecting shaft. The two ends of the torsion spring are respectively fixedly connected to the upper connecting rod and the upper connecting shaft. The end of the upper connecting rod away from the upper connecting shaft is rotatably connected to one end of the lower connecting rod. The other end of the lower connecting rod is rotatably mounted on the lower connecting shaft, and the lower connecting shaft is rotatably connected to the lower connecting rods of the multiple limiting components.

[0009] To better realize this application, the card shaft is further provided with an arc-shaped groove that matches the shape of the lower connecting shaft.

[0010] To better realize this application, a control box is further fixedly installed on the mounting plate, and a power source, including an electric cylinder, is provided inside the control box.

[0011] To better realize this application, the control box is further provided with an upper control plate and a lower control plate, both of which are connected to a power source. An upper cutting block is fixedly installed on the upper control plate, and a lower cutting block is fixedly installed on the lower control plate. The upper cutting block slides on the groove of the arc plate, and the lower cutting block moves within the side enclosed by the arc structure of the arc plate.

[0012] The technical solution provided in this application has the following advantages compared with the prior art:

[0013] 1. This application, by setting guide plates of different specifications and arrangements on the curved plate, can precisely control the spring pitch, and can produce mattress springs with different pitch combinations such as large pitch at the beginning and end and small pitch in the middle, so as to meet the diverse needs of mattresses in terms of comfort and support, and improve product competitiveness.

[0014] 2. The unique limiting component design of this application allows for easy loosening or fixing of the locking shaft by simply operating the connecting shaft. This facilitates the disassembly and adjustment of the guide plate on the inner mounting block, enabling rapid adjustment of the guide structure required for producing springs with different pitches. This saves production preparation time and improves production flexibility.

[0015] 3. The power source inside the control box of this application drives the upper and lower control boards and the cutting block to realize the automatic cutting of the spring strip; at the same time, the movement of the upper control board can drive the outer and inner rotating shafts to rotate, so that the outer and inner rotating rods rotate in opposite directions, jointly pushing the formed spring to detach. The whole production process is continuous and efficient, effectively improving production efficiency.

[0016] 4. The guide plate of this application adopts a spiral structure and its outer edge is rotatably connected to the inner arc surface of the arc plate, which can better adapt to the movement of the spring strip, accurately guide the spring strip to change direction and displacement, ensure the stability of the spring forming process, and improve the spring processing quality.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] like Figures 1 to 9 As shown, an extrusion molding structure for a mattress spring processing device includes a mounting plate 101. An upper mounting rod 102 and a lower mounting plate 116 are fixedly mounted on the mounting plate 101. An arc-shaped plate 103 is fixedly mounted on the upper connecting rod 112 and the lower mounting plate 116. The arc-shaped plate 103 has a semi-circular structure and is provided with an inlet groove and a rectangular groove. An outer mounting block 104 is fixedly mounted on the rectangular groove. The outer mounting block 104 is provided with multiple circular sliding grooves. A retaining shaft 105 is slidably mounted on the slide rail, and an inner mounting block 106 is fixedly mounted on the retaining shaft 105. The inner mounting block 106 is located on one side of the arc structure of the arc plate 103. Multiple guide plates for guiding the direction of the spring are fixedly mounted on the inner mounting block 106. An outer rotating shaft 118 is rotatably mounted on the lower mounting plate 116, and an outer rotating rod 119 is fixedly mounted on the outer rotating shaft 118. The processed mattress spring is pushed away from the guide plates and the arc plate 103 by the outer rotating rod 119.

[0030] Specifically, in use, the bed spring bar is guided by an external guide wheel to insert into the inlet slot on the arc-shaped plate 103. The arc-shaped structure of the arc-shaped plate 103 itself guides the spring bar, causing a change in its orientation in the vertical plane. Figure 1As shown, the vertical surface is the semi-circular interface of the arc plate 103, which causes the spring strip to bend. The first inner guide plate 107 and the first outer guide plate 108 provided on it provide further guidance, so that the spring strip undergoes lateral displacement. This lateral displacement is in the direction of the long side of the arc plate 103. After the spring strip bends, it rotates one revolution and inserts into the next set of first inner guide plates 107 and first outer guide plates 108. When it enters the second inner guide plate 109 and the second outer guide plate 110, the change in the curvature of the second inner guide plate 109 and the second outer guide plate 110 changes the lateral displacement again, that is, the pitch of the spring. By arranging and combining multiple sets of first inner guide plates 107 and first outer guide plates 108, and multiple sets of second inner guide plates 109 and second outer guide plates 110, the spring pitch is controlled. Different specifications and arrangements of first inner guide plates 107 and first outer guide plates 108, second inner guide plates 109 and second outer guide plates 110 can be set on the arc plate 103 to produce a unit of mattress spring, which can form different pitches, thus forming different products. In the mattress field, different effects can be achieved. For example, if the pitch of a spring is large at the beginning and end and small in the middle, when a person lies on the mattress, the surface of the mattress will easily sink in, improving the body's wrapping. After a certain degree, the internal sinking becomes more difficult, thus providing better support.

[0031] When the spring strip switches between different first inner guide plates 107 and first outer guide plates 108, second inner guide plates 109 and second outer guide plates 110, the pitch is repeatedly changed. After completing a unit of mattress spring, the spring strip is sheared to disconnect the spring in the arc plate 103 from the subsequent spring strip. The spring on the arc plate 103 is controlled by the rotation of the outer rotating shaft 118, which in turn drives the rotation of the outer rotating rod 119. The outer rotating rod 119 pushes the spring away from the arc plate 103, causing the spring to detach from the arc plate 103. With the rotation of the outer rotating rod 119 and the weight of the spring, the spring detaches from the outer rotating rod 119 and falls into the collection box below.

[0032] like Figures 6 to 9 As shown, the guide plate includes a first inner guide plate 107, a first outer guide plate 108, a second inner guide plate 109, and a second outer guide plate 110. The first inner guide plate 107 and the first outer guide plate 108 are a group and are disposed on an inner mounting block 106. The second inner guide plate 109 and the second outer guide plate 110 are a group and are disposed on an inner mounting block 106. The outer mounting block 104 is provided with a plurality of inner mounting blocks 106 with different guide plates. By setting the arrangement of the inner mounting blocks 106, the pitch of the mattress springs produced can be changed.

[0033] like Figure 2 , Figure 3 , Figures 6 to 9As shown, the guide plate has a spiral structure, and the outer edge of the guide plate is rotatably connected to the inner arc surface of the arc plate 103.

[0034] Specifically, multiple sets of guide plates are provided on the inner mounting block 106. The specifications of each set of guide plates can be adjusted as needed, as well as the placement of guide plates of different specifications. The first inner guide plate 107, the first outer guide plate 108, the second inner guide plate 109, and the second outer guide plate 110 all have a spiral structure. The spiral structures of the first inner guide plate 107 and the first outer guide plate 108 are the same. By setting the gap between them, the specifications of the spring strip are adapted, and the movement of the spring strip is guided, as well as the compression of the lateral displacement of the spring strip is applied to change the pitch of the spring. The second inner guide plate 109 and the second outer guide plate 110 work in the same way.

[0035] like Figure 5 As shown, a bracket is provided on the outer mounting block 104, and an upper connecting shaft 111 is rotatably mounted on the bracket. Multiple sets of limiting components are provided on the upper connecting shaft 111. The limiting components include an upper connecting rod 112, a torsion spring 113, and a lower connecting rod 114. The upper connecting rod 112 is rotatably mounted on the upper connecting shaft 111, and the torsion spring 113 is sleeved on the upper connecting shaft 111. The two ends of the torsion spring 113 are fixedly connected to the upper connecting rod 112 and the upper connecting shaft 111, respectively. The end of the upper connecting rod 112 away from the upper connecting shaft 111 is rotatably connected to one end of the lower connecting rod 114. A lower connecting shaft 115 is rotatably mounted on the other end of the lower connecting rod 114, and the lower connecting shaft 115 is rotatably connected to the lower connecting rods 114 of the multiple limiting components.

[0036] Specifically, such as Figure 5 In its current state, the upper connecting rod 112 tends to rotate counterclockwise due to the elastic force of the torsion spring 113. The left end of the upper connecting rod 112 pulls the upper end of the lower connecting rod 114, thereby pulling the lower connecting shaft 115 from the lower end of 114. This causes the lower connecting shaft 115 to push the retaining shaft 105 upward through the arc-shaped groove of the retaining shaft 105. Since the retaining shaft 105 can only slide laterally on the outer mounting block 104, the lower connecting shaft 115 fixes multiple retaining shafts 105, thereby fixing the first inner guide plate 107, the first outer guide plate 108, the second inner guide plate 109, and the second outer guide plate 110 on the inner side of the arc plate 103.

[0037] like Figure 5 , Figure 8 and Figure 9 As shown, the retaining shaft 105 is provided with an arc-shaped groove, which matches the shape of the lower connecting shaft 115.

[0038] The lower connecting shaft 105 is secured by the arc-shaped groove and the lower connecting shaft 115, and the spring force of the torsion spring 113 maintains this fixed state. When it is necessary to adjust the setting of the guide plate 1 on the inner side of the arc plate 103, simply control the lower connecting shaft 115 to move downward. The lower connecting shaft 115 pulls the lower connecting rod 114, and the lower connecting rod 114 then pulls the upper connecting rod 112 to rotate on the upper connecting shaft 111. As a result, the lower connecting shaft 115 disengages from the arc-shaped groove of the locking shaft 105. At this time, the lower connecting shaft 115 can be controlled to rotate around the axis of the left end of the upper connecting rod 112, so that the lower connecting shaft 115 moves to the outside of the locking shaft 105, thereby releasing the restriction on the lower connecting shaft 115. Under the action of the spring force of the torsion spring 113, the upper connecting rod 112 can be quickly driven to rotate, which will drive the lower connecting rod 114 and the lower connecting shaft 115 to move upward. At this time, the corresponding locking shaft 105 can be removed, and the guide plate on the inner mounting block 106 can be adjusted. The installation is the same.

[0039] like Figure 2 As shown, a control box 120 is fixedly installed on the mounting plate 101. The control box 120 contains a power source, including an electric cylinder, etc.

[0040] Specifically, an electric cylinder is installed inside the control box 120. The upper control plate 121 and the lower control plate 122 are moved up and down by the electric cylinder, thereby controlling the movement of the corresponding upper cutting block 125 and lower cutting block 126. The upper cutting block 125 and the lower cutting block 126 are used to cut the spring strip by cutting up and down, so that the mattress spring that forms a complete unit is detached.

[0041] like Figure 2 and Figure 3 As shown, the control box 120 is slidably provided with an upper control plate 121 and a lower control plate 122. Both the upper control plate 121 and the lower control plate 122 are connected to the power source. An upper cutting block 125 is fixedly provided on the upper control plate 121, and a lower cutting block 126 is fixedly provided on the lower control plate 122. The upper cutting block 125 slides on the groove of the arc plate 103, and the lower cutting block 126 moves within the side of the arc structure of the arc plate 103.

[0042] Specifically, when the upper control plate 121 moves, it drives the outer rotating shaft 118 and the inner rotating shaft 123 through the extension plate. Utilizing the threaded connection between the extension plate and the outer rotating shaft 118 and the inner rotating shaft 123, the outer rotating shaft 118 and the inner rotating shaft 123 are driven to rotate on the upper mounting plate 117 and the lower mounting plate 116. The rotation directions of the outer rotating shaft 118 and the inner rotating shaft 123 are opposite, thereby driving the outer rotating rod 119 and the inner rotating rod 124 to rotate respectively. Through the opposite rotation of the outer rotating rod 119 and the inner rotating rod 124, they jointly push the spring unit to disengage from the guide plate on the arc plate 103, thus completing one production cycle.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
